IMPROVEMENT lN PRESERVING FERMENTED LIQUORS.

Specification forming part of Letters Patent No. 150,288, dated April 28, 1874; application filed April 4, 1874.

To all whom it may concern:

Be it known that I, JOHN CLARK, of Washington, in the county of lVashington and District of Columbia, have invented a new and valuable Improvement in the Preservation of Fermented Liquors; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawings is a representation of a partial sectional elevation of the apparatus employed.

This invention has relation to the preservation of fermented liquors on draft; and it consists in the novel process of storing the excess of gas in an air-tight holder under pressure, in such a manner that less can be used in the beginning and more at the end of the draft,

thereby equalizing the pressure of the gas' accompanying drawings I have illustrated a, 7 simple apparatus by which an excellent purpose will be served.

In the accompanying drawings, the letter A designates the barrel or other receptacle holding the fermented liquor which is to be drawn. B indicates the spigot or draft-faucet; and C, stop-cock, to which a tube, E, is connected. F represents the gas-holder, which may consist of an exterior vessel, to, closed at the lower end, and an interior vessel, 1), having its upper end closed in sucha manner as to be air-tight, but communicating with the exterior vessel to by means of openings 0 at its lower end. The upper end of the interior vessel 12 is provided with tubes d and e, the former of which is provided with a stop-cock, while the latter serves for connection with the tube E, which communicates with the receptacle A.

The operation is as follows: The stop-cock of the tube cl being open to permit the escape of air, the vessel (0 is filled with water, which rises at the same time in the inverted vessel 1) to the height of the stopcock, above referred to, which is then closed. Upon opening the stop-cock C of the barrel or liquor-reservoir, the excess of gas therein is forced into the chamber 1) of the gas-holder, the water in said chamber being displaced by the gas andrising in the exterior vessel a. The stop-cock C may now be closed, and only opened occasionally as gas is needed in the reservoir A.

For the purpose of retarding the passage of foam through the tube-connection, while permitting the passage of the gas, I may employ a stuffing of sponge, wool, or other suitable porous material.

It will be observed, from the construction of this apparatus, that the gas which is taken from the reservoir A is returned thereto without coming in contact with atmospheric air.

Sometimes, instead of attaching the connectingpipe at the upper part of the barrel or reservoir, it may be desirable to attach it immediately at the spigot, and for this purpose Ihave provided a lateral stop-cock, a.

What I claim as new, and desire to secure by Letters Patent, is g The process of equalizing the gas-pressure on'fermented liquors during draft, by withdrawing from the barrel or other reservoir the excess of gas, and returning the same unvitiated by contact with air, substantially as,

specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
